I have done over 15 Airbnbs and this is the first time I felt the need to write a review because the condition of the apartment and response was so bad. I would feel guilty if I was the landlord renting this apartment out to someone.
The location is very awkward to reach by foot. It is on a back road and has cars and bikes whizzing down it. The general location near Phra Khanong is very good, but I do not think it's safe or recommended for someone without a car or bike. The actual unit has low ceilings only a bit over 7 feet.
The washing machine is an absolute nightmare and you will not be able to use it. It leaves half an inch of water on the patio and stays there smelling like mildew. I had many minor issues like hot water that I had to follow up multiple times to get a resolution, which was very annoying. Also- there is water damage in the bathroom, two lightbulbs out, two broken windows (one that shudders in the night and leaks a lot of cold air), and the A/C is old/loud.
